Computer Aided Design Using a Rational Quadratic Trigonometric Spline with Interval Shape Control

An important scheme is constructed to model 2D objects using a rational quadratic trigonometric function. The proposed rational quadratic trigonometric spline (RQTS) curve schemes because of having weight in its formation, is beneficial for shape modeling. The curve accomplished by the developed method, possesses the finest suitable geometric properties such as convex hull, partition of unity, affine invariance and variation diminishing. The parameter in the construction of proposed method is beneficial for imperative shape properties like global and local tension properties which is responsible for modifying the shape according to one's will. Moreover suggested scheme performance has smoothness of degree 2.
